Dr Andrew Armitage
I have a PhD in population genetics titled, ‘Alternaria leafspot pathogens: genetics, evolutionary history and diagnostics’ (University of Warwick). I hold an MRes in Biology and BSc in Ecology (Cardiff University).
My work focusses on genomics of perennial fruit species and their pathogens and pests, investigating the molecular mechanisms involved in host resistance to pathogens and pests.
I am currently working on the IDRIS (Improving disease resistance in strawberry) project as a bioinformatician. This project focuses on identifying effectors in plant pathogens and corresponding resistance genes in plant hosts. The outcomes of this work will: (a) Provide lists of genes associated with resistance to strawberry pathogens, which can be taken forward to breeding programs, and (b) generate web-based bioinformatic resources that can be used by the wider community. My role involves handling whole genome sequence data for the pathogens Phytophthora cactorum and P. fragariae, and sequence data from their strawberry hosts. I am also creating and running pipelines to perform genome assembly, gene prediction and effector identification.
My core research interest is the evolution of pathogenicity in plant pathogens and before joining the Harrison Lab I performed my PhD characterising the Alternaria alternata species group. This group of fungal pathogens is responsible for significant leaf spot diseases of fruit crops outside of the UK. As such I have experience in genome sequencing, phylogenetics, morphological analysis, investigating recombination and pathogenicity testing.
